Turnstiles & Barriers
High-speed vehicle boom barrier.
| Opening time | Typically 1.5 to 6 seconds by boom length |
| Boom length | Up to about 6 m |
| Detection | Ground loop or radar vehicle presence |
| Release | Card, plate recognition, intercom or push button |
A boom barrier is the standard control at a vehicle entrance: fast enough not to build a queue, and unambiguous about whether a car may proceed.
Revere pairs barriers with card, plate recognition or intercom release, and fits loop or radar detection so the boom never comes down on a vehicle.
